PLOW.

Specification of Letters Patent.

Patented Mar. 9, 1915.

Application filed December 12, 1913. Serial No. 806,148.

To all whom it may concern Be it known that I, FRANK E. DAVIS, a resident of La Crosse, in the county of La Crosse and State of Wisconsin, have invented certain new and useful Improvements in Plows, of which the following is a full, clear, and exact description.

The invention relates to plows.

In the operation of plows in'which the shares are raised and lowered by mechanism including a crank connected to-the furrowwheel at one side of the plow, it is customary to angle the spindle vertically to render the furrow-wheel effective to overcome side pressure, and it is desirable at times to angle the spindle horizontally to give the wheel more or less lead away from land,

to counteract side pressure.

The invention relates more particularly to the mechanism for adjusting and controlling the position of the wheel-spindle of these furrow-wheels.

One object of the invention. is to make provision for controlling the wheel spindle, so that its horizontal or vertical angle will not be changed when the crank-arm between the wheel and the plow-carrying structure is shifted, so that despite variationin the position or swinging of the crank, the angle of the wheel-spindle with respect to the horizontal or vertical will remain unchanged.

Another object of the invention is to provide improved means for adjusting the horizontal angle of the wheel-spindle to give it more or less lead.

Other objects of the invention will be apparent from the structure hereinafter set wheel, relatively to the land-wheel, being forth.

I The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings: Figure 1 is a plan of a plow embodying the invention. Fig. 2 is a side elevation. Fig. 3 is a perspective of the wheel spindle for the side furrow-wheel and its connections to the plow-carrying structure. Fig. 4 is a horizontal section through the bracket in which the wheelspindle is adjustably held, the spindle being shown therein.

The invention is shown asapplied to a gang-plow comprising a carryingstructure consisting of plow-beams 10, which are secured together at their rear ends by braces 11 and at their front ends by brackets 12 to which the draft-connection is secured. A

plowshare 14 is secured to each beam 10.

A land-wheel 15 is mounted on a spindle 16 on the outer end of a crank-arm 17 on a shaft 18, which is mounted in suitable bearings 19 which are secured to the beams 10,

respectively. The rear of the plow is vsustained by a trail-wheel 20 which is suitably mounted at the rear end of an arm 21 on a standard 22, which is pivotally held in a bracket 23, which is secured to one of this mechanism comprises a main lever 32,

which is rigid on shaft 18 and is adapted to p be locked in different positions by means of a lock-bolt 33 and a segmental rack 34 which is rigidly secured to one of the plow-beams 10. The operating connection between the main lever 33v and the crank-shaft 29, to which the side furrow-wheel is connected, comprises a lever 36,which is pivoted at 37 to lever 32, and a link 38' which is pivoted to lever 36, at 39, and to an arm 38 which is rigid on shaft 29. By adjustment of lever 32 along rack 34, the depth to which the shares are lowered my be varied. Lever 36 serves to effect adjustment of the furrownormally locked to a rack 41, which is rigid on the main lever 32 by a lock-bolt 42 carried by said lever. In operation, shift of lever 32 will raise or lower shafts 18 and 29 simultaneously to raise or lower both sides of the plow-carrying structure and the plows carried thereby. This mechanism thus exemplifies mechanism for-operating,

the crank-arm 28 to raise or lower the plowv carrying structure.

In practice, the arms of the furrow-wheel 27 is usually angled vertically to causethe wheel to resist sidewise movement toward upon the plows and sometimes it is also {i 2 I r 1 ,130,714

necessary: to angle the axis of this furrow I claim as new, and 'des'ire to secure myLet l'wheel horizontally to give the wheel more or less lead away from land according to' the character offlthe soil being plowed.

5W'hen the spindle for the side furrow-wheel has a crank-arm connected thereto,.adjustment of the crank-arm, resulting from shift of ithe 'operatingmechanism to cause the plow-share to travel at difierent depths,

varies the angle of the spindle or axis of the I wheel to give itmore or less inclination vertically and horizontally. To prevent this I variation, wheel-spindle 45, on which furrow-wheel 27 is jou'rnaled, is fixed .in' a 5 bracket 46, in which the out-turned end '28 Vof crank-arm 28 is pivoted, and the vertia carrying structure, carrying-wheels includ cality of this bracket is maintained or the bracketjis caused to move vertically without rotationpbya link 47, which has one of its ends pivoted jin bearingf and its other 7 end in a hug 48 at the upper end of bracket 46 this'link being substantially parallel to l \thecrank-arm 28 on operating shaft 29. As a a result'of this construction, bracket46' and 25 wheelspindle 45 will maintain their assigned vertical and horizontal angle despite pivotal movement of the shaft 29 and crank-J arm 28 in adjusting the plow-carrying structure, so that the angle of the wheel-spindle 3o 45 will not be varied during the operation of the plow-shifting mechanism.

The invention provides improved means for varying the horizontal angle of the wheel-spindle 45, so that the tendency of the V furrow-wheel to counteract side pressure a may be varied, and for' this'purp'ose, the bearing for thewhe'el-spindle 45 in bracket 46' is flared or elongated at one end, and ad justingscrews 51 and 52, at the front and rear of said bearing,are adapted to shift the wheel-spindle angularly and horizontally by tightening one of thefs'crew's and loosening the other. A set-screw 53, at the inner end of bracket 46 is adapted to secure the spindle against longitudinal movement and by loosening all of the screws slightly, the spindle 45, together with the furrowwheel 27, may be adjusted bodily. and laterally to travel at the desired point in the previously cut furrow. V

The invention thus'exemplifies a plow in which the carrying-frame or structure is connected to one of the furrow-wheels by means of a crank-arm and in which the angle 55 (of said wheel is. notdisturbed' by rocking of 4 the crank-arm to raise and lower the plowshares or their carrying-structure and in pended claims," without departing from'the' spirit and scope of the invention.

Having thus described my invention, what ters Patent, is:
